HORSE-POWER AND HOIST.

Specification of Letters Patent.

Application filed October 12,1906. Serial No- 338,570.

To all whom it may concern:

Be it known that I, ADAM M. SMITH, a citizen of the United States,residing at Whitewater, county of alworth, and State of Wisconsin, haveinvented new and useful Improvements in Horse-Powers and Hoists, ofwhich the following is a specification.

My invention relates to improvements in that class of horse-powers whichare adapted to be used both as a hoist for raising loads and as a powerfor driving various kinds of machinery; and it pertains more especially,among other things, first, to the means of communicating either acontinuous or inter mittent rotary movement from one or more sweeps ofthe power to a centrally-located revoluble hoisting-drum around whichthe hoisting-rope is adapted to be wound and upon and by which anendless belt, rope, or cable is adapted to be operated; second, to thedevice for manually controlling a reverse movement of the drum when thepower is being used for hoisting purposes as such drum is released fromthe sweep-actuating mechanism, whereby the elevating-carriage or loadsuspending from the free end of the hoisting-rope is free to descend orits own gravity and whereby the load may, if desired, be stopped andsuspended from the rope independently of the action of the horse or themovement of the sweep third, to the means of applying a brake to thehoistingdrum whereby the descent of the hoistingcarriage or other loadsuspended from the hoisting-rope may be controlled and regulated by themanual act of the driver; fourth, to the means employed forcommunicating a continuous rotary movement from the hoisting-drum to anendless belt, rope, or cable for.

driving machinery; fifth, to the trailing stop or arm carried by thesweep, which is adapted to arrest the rearward movement of the sweep asthe same is relieved from the action of the horse, whereby the horse isrelieved of the load or rearward pull upon the sweep which iscommunicated to it from the suspended load through the hoisting-drum andbrake mechanism when the brake mechanism is set while such load issuspended or being lowered, and, sixth, to the construction of thesweep, which is preferably made of two or more telescoping parts,whereby when the load is light or when desirous to increase the speed ofthe power said parts may be telescoped together, whereby the circledescribed by the horse will be shortened and the speed will beproportionately increased, also whereby when it is desirous to increasethe power of the horse said. telescoping parts may be drawn out and thesweep elongated, whereby the speed will be diminished and the power ofthe horse proportionately increased.

The construction of my invention is further explained by reference tothe accompanying drawings, in which- Figure 1 is a top view thereof, andFig. 2 is a vertical section.

Like parts are identified by the same reference characters in bothviews.

1 represents the hoisting-drum, which is revolubly supported at itscenter from a stationary frame 2 upon a collar 3 and at its peripheryfrom the supporting-frame 2 by a pluralityof rollers 4,roller-supporting pins 5, and pin-supporting bracket 6, and the same isretained in place by the central vertical shaft 4:, around which shaftthe drum is free to revolve. The shaft 4 is supported at its lower endin a socket formed therefor in said collar 3. Thus the hoisting-drum 1is free to revolve in either direction around the shaft 4 withoutrevolving said shaft while said shaft may be revolved a partialrevolution in either direction independently of said drum, whereby theoperator is enabled to communicate the required movement through saidcentral shaft to the drum-retaining pawl 6 for throwing such pawl intoand out of engagement with the annular ratchet 7 of the hoisting-drumregardless of the movement of said drum.

The pawl 6 is pivotally supported from the frame 2 upon the verticalstud 8 and is yieldingly retained in contact with said ratchet 7 by thespring 8 which spring is rigidly secured at one end to the stationaryarm 9 of said frame 2 by the retaining-pin 10. Mo tion is communicatedto said pawl 6 from the manually-actuated lever 11 through the link 12,pivot 13, arm 14, pivot 15, pawl 16, annular ratchet 17, shaft 4, arm18, pivot 19, link 20, and pivot 21, operating in the elongated slot 22,formed in said pawl 6. The slot 22 permits the required movement of thepawl 6pass the ratchet 7 without communicat-- ing motion from said pawlto the manuallyoperated mechanism connected therewith.

The lower end of the manually-actuated lever 11 is pivotally connectedwith the drivers platform 22 by the pin 23 and pinsupporting plate 24,the same being located in close proximity to the drivers seat 25.

It will be understood that the drivers platform 22 and seat 25 andoperating-lever 11 are all supported from the inner end of one of thesweeps and that they maintain the same relative position to each otherand are adapted to revolve either with or independently of thehoisting-drum, as the same are being revolved by the action of thehorse.

Motion is communicated to the drum 1 from the sweep 26 through theflexible clamping-band 27, one end of said clamping-band being pivotallyconnected to the sweep 26 by the bracket 28, said band being carriedfrom thence around the periphery of the hoistingdrum, and from thence tothe arm 29 of the three-armed lever 29, the central arm of the lever 29being pivotally connected with the end of the sweep 26 by the bolt 30,while the draft mechanism 31 is connected with the other arm of thelever 32 by the connectinglink 33. Thus it will be understocdthat as thepower of the horse is applied to the draft mechanism 31, saidthree-armed lever will be caused to turn a partial revolution upon thebolt 30, whereby the band 27 will be put under the required tension forclamping the hoisting-drum, thus causing the drum to revolve with thesweep as the latter is being moved forward in a circular course by theaction of the hoist. 34 represents the hoist ing-rope, which as thehoisting-drum is revolved is wound upon the periphery of the samebeneath the clamping-band. 1t will be understood that the hoisting-rope34 is guided to and from the hoisting-drum by the guiding-pulley 35 inthe ordinary manner, said pulley 35 being revolubly supported upon thevertical shaft 36, which shaft is in turn supported from the frame 2 ofthe horsepower by the bracket 37. It will now be understood that whenthe rope 34 has been connected with an elevated pulley and the free endconnected with a load which it is desirous to elevate motion will becommunicated from the sweep to the hoisting-drum through theclamping-band 27, whereby said drum will be caused to revolve with thesweep, thereby winding the hoisting-rope 34 upon its periphery until theload has been elevated. When the load has been thus elevated andremoved, the load-carrying carriage or lifting mechanism connected withthe free end of the rope will be free to descend of its own gravity byreleasing the clamping-band 27 upon the periphery. of the hoisting-drum,when said drum will be free to revolve in the opposite direction untilthe carriage connected with the free end of the rope has descended tothe starting-point. The tension of the clamping-band 27 is released bystopping the horse and releasing the pull upon the draft lever 42, pivot43, lever 44, pivot 44, and.

flexible band connection 45, which band 45 is connected at its oppositeend from said arm 44 with said clamping-band 27 by the fasteningmechanism 46. Thus it will be understood that the same clamping-bandwhich is used for communicating the revolving movement from the sweep tothe hoistingdrum also serves the additional purpose of a frictionclamping-band for retarding the re- .verse movement of the drum and thesame is controlled, as stated, by the manual act of the operator. Levers1 1 and 38 are provided with ordinary hand actuated pawls and ratchetsfor locking them at any desired point of adjustment.

It will be understood that the forward or reverse movement of thehoisting-drum, communicated to it either by the horse or by the weightof the descending carriage or other mechanism suspended therefrom, isthus completely under the control of the operator and that the operatingmechanism for thus controlling the hoisting-drum is in a convenientreach of the operator. The same is also at all times in the samerelative position to the drivers seat and platform.

To relieve the horse from the load suspended from the hoisting-rope whendesirous to stop the power when the load is suspended therefrom, Ipreferably provide the outer end of the sweep 26 with a trailing arm 47,the upper end of which is pivotally connected with the sweep, while thelower end is adapted to trail upon and engage in the surface of theground or track, whereby it is obvious that as soon as the horse ceaseshis forward movement and the draft mechanism becomes slack the rearwardmovement, which would otherwise be communicated to the sweep from thesuspended load, will be resisted by said trailing arm.

The sweep 26 is preferably formed in two or more parts A and B, whichare telescoped or otherwise adjustably connected together, as shown atC, when they are secured at the desired point of adjustment by thelock-nut D or in any convenient manner.

It will be understood that when the sweep 26 is thus made in two partsit will become necessary to connect the clamping-band 27 adjustably withthe lever 29, whereby the length of said clamping-band may be inmechanism. To prevent the hoisting-carl creased or diminished tocorrespond with the length of the sweep when it is extended andcontracted. To accomplish this object, I preferably interpose anintermediate connection E between the lever 29 and said clamping-band27, and such parts are adjustably connected together by the transversepin I, which is inserted through one of the several apertures G of saidclamping-band and corresponding apertures formed in said intermediateconnection E, or such parts may be connected together in any convenientmanner.'

When desirous to use my horse-power both as a hoist and as a means fordriving machinery, I provide the drum 1 with an endless belt 50, whichencircles the drum and is led therefrom to the machinery to which it isdesirous to operate thereby.

To prevent the endless belt 50 from slipping on the drum, I preferablyprovide the same with a plurality of V-shaped or angularcontact-bearings 51, which are connected at short distances apart aroundthe periphery of the drum for the reception of said endless belt,whereby the same is prevented from slipping. The endless belt thus usedmay be of ordinary rope or metallic cable, as circumstances require.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a horsepower of the class described the device for communicating arotary movement from the movable sweep to a hoistingdrum, consisting inthe combination with the sweep and drum of a flexible clamping-band,means for connecting one end of said band to the sweep in closeproximity to said drum and means for connecting the other end of saidband to the draft mechanism carried by the sweep, whereby the pull uponthe draft mechanism and sweep will simultaneously tighten theclamping-band around the periphery of the drum and cause said drum tomove with the sweep.

2. In a horsepower of the described class the device for manuallycontrolling the reverse movement of the hoisting-drum consisting of thecombination of a manuallyoperated lever pivotally connected with asweep-actuated platform, a two-armed lever pivotally connected with thesweep a link connected at one end with said manually operated lever andat its opposite end with one of thearms of said two-armed lever, a

drum encircling clamping-band and a flexible connection connected at oneend to one of the arms of said two-armed lever and at its opposite endwith said drum-encircling clamping-band.

3. In a horse-power of the described class, a device for manuallythrowing a pawl into and out of locking engagement with the annularratchet carried by the hoisting-drum, consisting in the combination of ahand-actuated lever pivotally connected with a sweepsupported platform,a lever revolubly connected at one end with a central drum-retainingshaft, a link connected at its respective ends with said leversrespectively, a ratchet-wheel rigidly connected with the upper end ofsaid central shaft, a pawl connected at one end with said revolublelever and adapted to engage at its opposite end with said ratchet-wheel,an arm rigidly connected with the lower end of said central shaft, apawl pivotally supported from the drum-supporting frame and adapted toengage the annular ratchet carried by said drum, a link connected at oneend to said pawl and at its opposite end to said shaftactuated lever,whereby as said sweep-supported lever is inclined forwardly andbackwardly upon its supporting-pivot said pawl will be thrown into andout of engagement with the annular ratchet of said drum, substantiallyas set forth.

4. In a device of the described class the combination with ahoisting-drum of a plurality of angular contact-bearings formed in aseries around the periphery of said drum in combination with an endlessbelt, all sub stantially as and for the purpose specified.

5. In a device of the described class the combination with a revolublehoisting-drum of an extension-sweep formed of two parts slidablyconnected together, the inner end of said. sweep being pivotallyconnected with said drum-supporting shaft, means for detachablyconnecting said. sweep with said drum both automatically and manually,and means for locking the members of said sweep at any desired point ofadjustment.

In testimony whereof I affix my signature in the presence of twowitnesses.
